Abstract
Using the DTPA extraction procedure and a graphite furnace atomic abso rption spectrophotometer, a practical method for determining soil cadm ium levels was developed. Furnace parameters, instrument parameters, s olvent dilution factor, and solvent characteristics were determined us ing experimental field samples and standardized control samples. The D TPA extraction method gave reproducible results and removed approximat ely 20 to 60% of total soil cadmium.
